Be it known that lA7 Joni; l". CoNNoR,'

citizen of the United States, residing at Chicago, in the county of Cook and Statepf illinois7 have invented a certain new and useful Improvement in Trait-Rigging for VRailway@ars, of whiclithe following is a `a draft rigging embodying "Amy invention;

preferably the` rivets 17e-17.' The stop members are counterparts of each other., and we therefore will describe only one. Each stop member 6 comprises a stationary p0rtion 18 rigidly secured tothe adjacent draft member, and a movable portionl) adapted to co-act therewitl'i;` The stationary portion 178 comprises a web 20 having transverse flanges 21 and 22 at the front and rear ends 1 thereoit'-,w respectively forminmrtront and rear .shoulders adaptedto limit 'the' movements of Vthe movable portion 19 oi the stop membei'. 'The stationary portionlS of the'stop member is also provided with 'verticali spacednpart 4upper and lower Viii-turned iianges 23 and 2l, respectively 'forming a groove orguide with-in which-the movable portion 19 of the stop menibermis partially received. `Within the groove" between the shoulders itl-and- 22 is mounted, at intervals, a :plurality'of upper and lower stops 25 and 26respectiyely, the

said upper `stops 25 being preferably integral with the adjacent `web2O-of the' stationary member i8, and the Vlower stops being preferably integral witlrthelower flange 24 and the said web-20. The stops 25 and 26 are suitably spaced-maart vertically Ato -permit reciprocating movement between them of stops upon the movable member 19 to be. hereinafter described. In the intervalsy 27 between the upperl'stops and the interfvals between the lower stops 26 are mountedsprings 29, the said spi-inw* Os being `preierably dat plates grouped as illustrated in Fig. 2 o' the dra\vi1.1gs,.'and extending vertically at intervals throughout the length of the ,stop member,V between lthe shoulders 2l and-22 of the stationary member 18. The stops 25 and 2G are 'each preferably curved, as shown at the numeral 30, to permit the ,flexing oi' the springs 29 in either direction while the ends of said springs are held between the stops hereinbelore described. The movable memberl) of each stop inember consists "of a plate having a vertical longitudinally reitending` web Shan upper erse outwardly er,tendisii;V flange 32 which is received within a longitudinally' extending way between the upper edges oi the stops and the langeQ- oi' the stationary nileinber 1 8; 0n the inner face oi f the web 3i are arranged, at intervals corresponding substantially i with. tbe'intervals between the upper stops 25 `and the lower stops 26 of the stationary member 18, stops 84, 'which are preferably integral with the web 31, the said stops in preferable construction having front and rear convex bearing faces, as indicated at the numerals 35-'35 in Fig. 2 of the drawings. rfhe stops 34-are suitably spaced apart longitudinally to receive between them each a set of springs 29. In' preferable construction, therefore, the stops 34 of the movable member 19 equal in number the stops 25 or the stops 26 of the stationary member 18. The movable member 1 9 is provided on its face opposed to the draft gear 7 with a rear stop shoulder 38, a front stop shoulder 39, and limiting stop shoulders 40 and 41.

On rearward movement of the draw-,ban the draft gear is. stopped by the rear stop shoulders 38 of the movable portion 19 of the stop members, the draw-bar thrust being transmitted from the movable members to. the stationary members 18 through/the series of resisting springs 29, which are flexed reamrwardly by the relative rearward movement of the stops 34 on the movable member 19, and are held at their ends by 'the stops 25 and 26 upon the stationary member 18.

Upon" full compression of the draft gear,.

the rearward movement of the-front follower is limited by its engagement against the limiting stop shoulders 40. lf the compression resisting power of the combined springs 29 is arranged so as to be greater than that of the draft gear, then with a sufficiently heavy rearward thrust vof the draw-bar to close the draft gear, the fur ther rearward movement of the draw-bar 'in reference to the draft members will be permitted until the entire shock absorbing capacity of the resilient'stop members has been exhausted.

On forward movement of the draw-bar, the draft gear is stopped at its forward end by the front stop shoulders 39 through the medium of the front follower l2, and thev forward movement of the draw-bar is resisted by the draft gear 7 and also by the resilient stop members, ina manner similar to that described in connection with the rearward movement of the draw-bar. rllhe forward movementlof the draft gear is limited by the limiting stop shoulders 41, which Iin the specific type of draft gear illustrated in the drawings engage the forward edges of the spring case 46 of the draft gear.

The further action is similar .to that on rearward movement ofthe draw-bar, and, as will be obvious, will be in some measure dependent upon thefrelative compression resisting4 capacity ofthe resilient stop members and the 'draft gear.v

It will be apparent that, with stop meme bers, which are within themselves resilient and draw-bar resisting, a high spring ref sistance in addition tothe resistance af'' Lafraise forded by the draft gear pifoper, may be had, and also by the interpositioinof the resilient stop members between the draft gear and the under-frame of the car, thedzotal draw bar movement may be increased"-over the movement of the draft gear. Thus, `with my invention, not only is a high capacited draft rigging aiforded, but the shock absorbing lcapacity of draft gears can be highly supplemented by the use of my resilient stop members, and draft gears' with comparatively short movement may by the usc of the said resilient stop members afford the draw-bar a longer movement when conditions of railroad service make such longe:l movement desirable. ltis also apparent that by varying and changing the size and shape of the stops 25, 2G or 34, the springs 29 may lbe brought into action in series or one after another.
